Calibration Masses

Calibration masses are available in electronic balance and precision analytical. Electronic balance calibration masses are cylindrical shaped for easy stacking on balance weighing pans. Precision analytical calibration masses feature two-piece construction and consist of a special austenitic alloy for high precision and stability. Both types of calibration masses meet ASTM Class 1 or ASTM Class 4 standards and are available with either a NVLAP Lab Code 105013-0 (National Voluntary Laboratory Accreditation Program) or traceable certificate.
